APPARATUS FOR COOLING AND PURIFYING AIR UNDER PRESSURE.

SPECIFICATION forming part of Letters Patent N 0. 638,327, dated December 5, 1899.

Application filed May" 5 1898. Serial No. 679,838. (No model.)

T0 to whom it may concern:

Be it known that I, JOSEPH GEISENBERGER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Cooling and Purifying Air Under Pressure, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of an apparatus for cooling and purifying air under pressure, the same being adapted to be directed into a keg or other receptacle for beer or other fluid for discharging or dispensing the latter.

Figure 1 represents a perspective view, partly broken away, of the purifying and cooling chambers in detail. Fig. 2 represents a vertical section of the purifying and cooling apparatus embodying my invention.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates an ice-box or, refrigerator-case, within which are supported the rack B and the coils O, the latter being superimposed 011 said rack and having ice placed thereon for cooling said coils, the latter being adapted to have beer or other fluid pass therethrough in order to be cooled in its passage to the spigots or place of discharge within the case.

Below the rack 13 are the cylinders or chambers D, which are in communication by means of the pipes E and have within them the packing F and the strainers and guards G at the ends of said packing for preventing spreading thereof and trapping dust or dirt that may enter the first cylinder of the series, which cylinder has connected with it the pipe H, leading from a pump or other.

means of supplying air thereto under pressure. The last cylinder of the series has connected with it the pipe J, which leads therefrom to a keg or other receptacle for the beer or fluid to be subjected to pressure for discharging or dispensing purposes.

Since the air-pump or air-forcing device from which the pipe H leads and the faucet or bunging apparatus to which the pipe J leads are so well known and of such common construction, it will be unnecessary to illustrate the same.

The packing D consists of material having the quality of purifying the air passed therethrough. Consequently as the cylinders are subjected to the action of the refrigerant in the case A the air "directed into the keg or receptacle will be both purified and cooled, the effect of which in the beer or fluid is evi dent.

The number of coils C and cylinders may be increased or decreased,as desired. The cylinders are provided with caps K, which may be removed in order to provide access to the interior of the former for purposes of cleansing, repairs, 850.

The packing employed may be medicated cotton, animal-bone charcoal, broken stone, sand, &c., such material being used in different combinations and distributed throughout the series of cylinders, as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination with a refrigerator-case having an ice-rack, a coil of pipes superimposed upon said rack with the end thereof extending through the sides of the case and adapted to communicate with suitable supply and delivery pipes, of a plurality of communicating purifying-chambers situated below said ice-rack, said chambers being provided with packing, strainers or guards at the ends of said chambers, the first of said chambers communicating with a source supplying air under pressure, and the last of said chambers being provided with an outlet leading to a place of service.
